[Embodiment 1] This embodiment shows an example of a route guidance device 100 mounted on a vehicle. However, it goes without saying that the route guidance device 100 is not limited to vehicles, and can be applied to any mobile body including boats, ferries, and the like. Further, the route guidance device 100 can also be applied to information processing devices such as vehicle control devices, smart phones, tablet PCs (Personal Computers), various IT (Information Technology) devices, game machines, and the like.

FIG. 1 is a diagram showing a configuration example of a route guidance device. The route guidance device 100 has at least a processing section 110 and a storage section 120 . In addition, the route guidance device 100 has an input unit 131 , a display output unit 132 and an audio output unit 133 . The processing unit 110 includes an input control unit 111, a display unit 112, a voice control unit 113, a route guide unit 114, a route setting unit 115, a position acquisition unit 116, a date and time acquisition unit 117, and a day of the week acquisition unit. 118 and a route editor 119 are included. The storage unit 120 stores route information 121 , guidance display information 122 , guidance voice information 123 , map information 124 , and in-vehicle device information 125 .

FIG. 2 is a diagram showing an example of the data structure of route information. The route information 121 includes a driving start position 121b, a driving start time 121c, an applicable day of the week 121d, an applicable period 121e, and detailed route information 121f for each route ID 121a. In the detailed route information 121f, a departure node 121g, a traffic link 121h, a destination node 121j, a guidance point 121k, and a guidance display 121m are stored in association with each other. An identifier that uniquely identifies a route is stored in the route ID 121a. In addition, the route in this embodiment is determined in advance and refers to a plurality of route routes. It should be noted that the route is information specifying a traveling road/route that continuously connects a predetermined departure point to an arrival point. For example, in a fixed-route bus, each predetermined route includes a route of a fixed traveling road connecting a departure point to an arrival point, and each route can be said to be a route. Of course, it can be said that routes exist not only for route buses, but also for shuttle buses, highway buses, water buses, ferries, etc., as long as they have similar characteristics. As long as no traffic restrictions are imposed on any of these routes, the vehicle travels and navigates according to a fixed route without being influenced by variable factors such as traffic congestion.

The driving start position 121b is information specifying a position at which driving is started on a route, that is, a position that is the starting point of the route. The driving start time 121c is information specifying the time to start driving on the route, that is, the time to start moving on the route. The applicable day of the week 121d is information specifying the day of the week to which the route is applied. The application period 121e is information specifying a period (minimum one day) during which the route is applied. The applicable day of the week 121d and the applicable period 121e are optional elements determined according to setting requirements, and are not essential settings. That is, when nothing is set in the applicable day of the week 121d, the route is applied to all days of the week regardless of the day of the week. Also, if nothing is set in the applicable period 121e, the route is applied to all days regardless of the date.

Further, for each route ID, the detailed route information 121f, which is route information in which predetermined points on the map are set as nodes and roads between the nodes are set as links, is provided. A route can be subdivided into a set consisting of a set of a departure node, a travel link, and an arrival node, which indicates a movement in one direction, and which are continuously connected (the destination node is the next movement node). originating node). Such itineraries are stored in origin node 121g, traffic link 121h, and destination node 121j as a sequence of minimal sets.

The guidance point 121k is information for specifying a reference point for guidance when some kind of route guidance is to be provided. Basically, when the moving object approaches within a predetermined distance of the point indicated by the guide point 121k, route guidance is provided. However, if the guide point 121k is not set, it indicates that route guidance will not be provided when passing through the traffic link.

The guidance display 121m is information specifying a fixed output pattern for route guidance when the guidance point 121k is set. For example, predetermined displays and voices are provided in advance as guidance displays, such as a pattern for guiding a right turn at a T-junction, a pattern for guiding straight ahead at a crossroad, or a pattern for guiding lanes on an elevated road at the entrance of an elevated road. . Thus, the information specifying the guidance display to be output at the guidance point 121k is stored in the guidance display 121m.

FIG. 3 is a diagram showing an example of the data structure of guidance display information. In the guidance display information 122, a display screen 122b and an output sound 122c are stored in association with each guidance display 122a. The display screen 122b and the output voice 122c are output information used for guidance, and are displayed and spoken in the route guidance device 100, respectively.

FIG. 4 is a diagram showing an example of the data structure of guidance voice information. The voice guidance information 123 includes a voice output identifier 123a, an output voice 123b, and a variable 123c in association with each other. The audio output identifier 123a is information specifying audio to be output at the time of notification.

The output sound 123b is information specifying a language sound (speech) or sound effects (beep, chime, etc.) to be uttered at the time of notification. The variable 123c is information that replaces the metacharacter shown as a variable in the output speech 123b. For example, if the variable 123c contains "[route 1]: next intersection name", the part corresponding to [intersection 1] in the utterance "turn right at [intersection 1]" included in the output speech 123b is This is the information that designates to be replaced with the next intersection name on the route and uttered.

Returning to the description of FIG. The map information 124 is information for constructing a map. Specifically, the map information 124 includes link information related to roads on the map, area information for identifying areas on the map, and the like. Link information includes, for example, point coordinates of a start node and an end node indicating both ends of a road, road type information indicating the type of road such as national road, toll road, and prefectural road, and link length information indicating the length of the road. , link width information indicating the width of the road, link direction information indicating the direction of the road, travel time information indicating the time required to pass the road, and connecting to each of the start node and the end node of the road. start connection link/end connection link information in which the link ID of the road is stored.

The vehicle-mounted device information 125 is information for identifying an individual device when the route guidance device 100 is a vehicle-mounted device. If the route guidance device 100 is mounted on a ship, it is not appropriate to call it vehicle-mounted device information, but in the present invention, it is called vehicle-mounted device information for the sake of convenience.

The input control unit 111 detects an input to an operation button or the like. Specifically, the input control unit 111 detects input by the user, mainly touch input from the touch panel, and identifies input coordinates and input types (tap, long tap, flick, pinch, etc.). Alternatively, the input control unit 111 receives an input from a user through a hardware button (for example, a button for adjusting volume). The display unit 112 constitutes a display screen. The audio control unit 113 configures audio information (including language audio, sound effects, music, etc.).

The route guide unit 114 guides the traveling direction of the moving body using information on a selected route, which is one route selected from a plurality of predetermined routes. Note that the plurality of predetermined routes correspond to routes in the case of fixed-route buses and water buses. Moreover, even when there is only a single route, it may be expressed as a plurality of routes for convenience. Here, the selected route is route information acquired by the route setting unit 115 .

The route setting unit 115 acquires predetermined route information. When the acquired route information is referred to as a selected route, the route setting unit 115 acquires the route information corresponding to the position of the moving object and the current time as the selected route among the plurality of pieces of route information included in the route information 121 . Further, when the route information includes the designation of the applicable day of the week, the route setting unit 115 narrows down the route information to the route information including the applicable day of the week acquired by the day of the week acquiring unit 118, and acquires the route information as the selected route. In addition, when the route information includes the designation of the date to be applied (each day in the applicable period), the route setting unit 115 sets the date acquired by the date and time acquiring unit 117 to the applicable period (day). Narrow down to the included route information and acquire it as a selected route.

In addition, the route setting unit 115 allows a predetermined error in the position of the moving object in the process of acquiring predetermined route information from a plurality of pieces of route information, and determines the correspondence. That is, for example, the position of the moving object includes an error of about 100 m in circumference, and the route setting unit 115 does not require strict matching with the operation start position. In addition, the route setting unit 115 allows a predetermined error for the current time in the process of acquiring predetermined route information from a plurality of pieces of route information and determines the correspondence. That is, for example, the current time includes an error of about 5 minutes, and the route setting unit 115 does not require strict coincidence with the driving start time. As a result, it is possible to operate with a certain amount of time, so that it is possible to avoid a situation in which an unintended route is erroneously set.

Alternatively, the route setting unit 115 is not limited to the route information included in the route information 121. For example, the route setting unit 115 receives predetermined route information via communication from a predetermined device (such as a server device accessible by communication via the Internet). may be acquired.

The position acquisition unit 116 acquires information on the position of the moving body on which the route guidance device 100 is mounted. The date and time acquisition unit 117 acquires the current time from a GPS (Global Positioning System), system clock, or the like. The day-of-the-week acquisition unit 118 acquires the day of the week associated with the current time. The route editing unit 119 provides an interface for the user to edit the route information 121 , the guidance display information 122 and the guidance voice information 123 . For example, the route editing unit 119 provides a predetermined route editing screen, and uses information input by touch input or keyboard input to create route information 121, guidance display information 122, and guidance voice information 123. Accept edits.

The input unit 131 receives input from an external device such as an operation button or a touch panel, and transfers the input information to the input control unit 111 . The display output unit 132 controls display of the display screen configured by the display unit 112 . The audio output unit 133 controls output of audio information (including language audio, sound effects, music, etc.) configured by the audio control unit 113 .

In recent years, public transportation systems such as fixed-route buses and water buses, as well as transportation networks such as shuttle buses and express buses, have developed and become more complex. It's getting complicated. Drivers are not limited to one route, and may drive on multiple routes on a daily basis. Misunderstanding of the route in charge is becoming more likely to result in incorrect setting of the route.

In view of the above, the route guidance device 100 allows the driver, who is the user, to receive route guidance without setting the route. As a result, erroneous route setting due to human error can be avoided, and stable operation of the transportation network can be realized.

FIG. 5 is a diagram showing a hardware configuration example of the route guidance device. The route guidance device 100 includes a processor (for example, CPU or GPU) 101, a memory 102 such as a RAM (Random Access Memory), a storage device 103 such as a hard disk device (HDD) or an SSD, and communication via a network. It can be realized by a general information processing device including a communication device 104 serving as an interface for connection, a display 105, a touch panel 106, a GPS 107, a storage media reader 108, and a bus connecting these to each other. Note that the GPS 107 is not limited to this, and any device capable of positioning may be used. For example, devices using satellite positioning systems such as Glonass (Global Navigation Satellite System), Michibiki, Galileo, and Beidou may be used.

Each functional unit of the processing unit 110 described above, that is, the input control unit 111, the display unit 112, the voice control unit 113, the route guidance unit 114, the route setting unit 115, the position acquisition unit 116, and the date and time acquisition unit 117 , the day-of-the-week obtaining unit 118, and the route editing unit 119 are constructed by the processor 101 reading and executing a predetermined program. Therefore, the memory 102 or the storage device 103 stores a program for realizing the processing of each functional unit. The program is loaded into the memory 102 at the time of execution and causes the processor 101 to perform processing.

The route information 121 , the guidance display information 122 , the guidance voice information 123 , the map information 124 and the in-vehicle device information 125 are realized by the memory 102 or the storage device 103 .

FIG. 6 is a diagram illustrating an example of a processing flow of route setting processing. The route setting process is started when the route guidance device 100 is operably activated. In the present embodiment, since the route guidance device 100 is mounted on a moving body, it is operably activated at the timing (ACC_ON) when the accessory power source of the mounted moving body is turned on. The route setting process automatically sets a route where the current position and time approximately match the driving start position and driving start time. In addition, if there is an applicable day of the week as an optional setting item, this is appropriately reflected. It is a process to That is, if the day of the week corresponds to the applicable day of the week, the route is set as the setting target, and if not, the route is set by excluding the route from the setting target.

First, the date and time acquisition unit 117 acquires time (step S001). Specifically, the date and time acquisition unit 117 acquires the current date and time and identifies the time. Then, the position acquisition unit 116 acquires information on the position of the mobile object (step S002). Specifically, the position acquisition unit 116 acquires coordinate information such as latitude and longitude information of the current location.

Then, the route setting unit 115 identifies a route having approximately the same time and position (step S003). Specifically, the route setting unit 115 refers to the route information 121 using the time acquired in step S001 and the information on the position acquired in step S002 to determine the operation start time 121c and the operation start time 121c, respectively. Route information within a predetermined error range from the position 121b is specified.

Day-of-the-week obtaining unit 118 then obtains the day of the week (step S004). Specifically, day-of-the-week acquisition unit 118 acquires the day of the week corresponding to the current date and time acquired by date-and-time acquisition unit 117 in step S001.

Then, the route setting unit 115 determines whether or not it is the applicable day of the week for the route (step S005). Specifically, the route setting unit 115 determines whether the information on the day of the week acquired in step S004 matches or includes the applicable day of the week 121d related to the route identified in step S003. For example, when "weekday" is set in the applicable day of the week 121d, if the day of the week obtained by the day of the week obtaining unit 118 is Monday to Friday, the route setting unit 115 determines that it is the applicable day of the week for the route. .

If it is not the applicable day of the week for the route (“No” in step S005), the route setting unit 115 determines whether or not the applicable day of the week is set for the route (step S006). Specifically, if any day of the week is set in the applicable day of the week 121d associated with the route identified in step S003, the route setting unit 115 determines that the route has the applicable day of the week set. If the route has the applicable day of the week set (“Yes” in step S006), the route setting unit 115 assumes that there is no route that matches the applicable day of the week, and performs route setting processing without automatically setting the route. terminate.

If there is no applicable day of the week set for the route (“No” in step S006), or if the route is applicable on the day of the week (“Yes” in step S005), the route setting unit 115 is set to cause the route guidance unit 114 to start route guidance (step S007).

The above is the flow of the route setting process. According to the route setting process, even if the driver who is the user does not set the route, route guidance can be received.

7 and 8 are diagrams showing an example of route setting 300 and an example of route setting 350 at another location. For example, it is assumed that the route information 121 includes a route 310 (route A) that starts driving from point P at 8:00 am and reaches point Q following a fixed route. Note that the route information 121 also includes a route 360 (route B) that starts driving from point Q at 8:00 am at the same time and follows a fixed route to reach point R shown in FIG. do.

In this case, if the moving body on which the route guidance device 100 is mounted is located at point P at 8:00 am, the route guidance device 100 moves from point P to point Q as shown in the example of FIG. A route can be automatically set as a selected route.

Similarly, if the moving body equipped with the route guidance device 100 is located at the point Q at 8:00 am, the route guidance device 100 travels from the point Q to the point R as shown in the example of FIG. Route B can be automatically set as the selected route.

FIG. 9 is a diagram illustrating another example of the processing flow of route setting processing. In another example of the process flow of route setting processing, routes can be set by date. The above-described route setting process is a process for automatically setting a route when the current position and time substantially match the driving start position and driving start time, and when the applicable day of the week corresponds to the corresponding day of the week. Another example of the route setting process is the process of appropriately reflecting the applicable period (days) when there is an optional setting item. That is, if the date corresponds to the applicable period, the route is set as the setting target, and if not, the route is set by excluding the route from the setting target.

Steps S001 to S003 are the same as the route setting process described above, so descriptions thereof will be omitted. After specifying the route in step S003, the route setting unit 115 determines whether or not there is a setting for the application date of the route (step S104). Specifically, the route setting unit 115 determines whether or not the applicable period 121e of the target route information 121 includes any value.

Then, if there is a setting for the application date of the route ("Yes" in step S104), the date and time acquisition unit 117 acquires date information (step S105). Specifically, the date and time acquisition unit 117 acquires the date (year, month and day) corresponding to the current date and time acquired in step S001.

Then, the route setting unit 115 determines whether or not it is the application date of the specified route (step S106). Specifically, the route setting unit 115 determines whether or not the date information acquired in step S105 matches or is included in the application period 121e of the route information 121 of interest. For example, if the applicable period 121e includes a date specified by the current date and time, the route setting unit 115 determines that the applicable date is the route applicable date.

If it is not the application date of the route (“No” in step S106), the route setting unit 115 terminates the route setting process without automatically setting the route, assuming that there is no route that matches the application date. .

If it is the application date of the route ("Yes" in step S106), the route setting unit 115 sets the route and causes the route guidance unit 114 to start route guidance (step S107).

If there is no application date setting for the route (“No” in step S104), the route setting unit 115 determines whether or not there is an application day of the week for the route (step S108). Specifically, if any day of the week is set in the applicable day of the week 121d associated with the route identified in step S003, the route setting unit 115 determines that the route has the applicable day of the week set.

If there is no applicable day of the week set for the route ("No" in step S108), the route setting unit 115 advances the control to step S107 and causes the route guidance unit 114 to start route guidance.

If the route has an applicable day of the week (“Yes” in step S108), the day of the week obtaining unit 118 obtains the day of the week (step S109). Specifically, day-of-the-week acquisition unit 118 acquires the day of the week corresponding to the current date and time acquired by date-and-time acquisition unit 117 in step S001.

Then, the route setting unit 115 determines whether or not it is the applicable day of the week for the route (step S110). Specifically, the route setting unit 115 determines whether the information on the day of the week acquired in step S109 matches or includes the applicable day of the week 121d related to the route specified in step S003. For example, when "weekday" is set in the applicable day of the week 121d, if the day of the week obtained by the day of the week obtaining unit 118 is Monday to Friday, the route setting unit 115 determines that it is the applicable day of the week for the route. .

If it is not the applicable day of the week for the route ("No" in step S110), the route setting unit 115 terminates the route setting process without automatically setting the route.

If it is the applicable day of the week for the route ("Yes" in step S110), the route setting unit 115 advances the control to step S107 and causes the route guidance unit 114 to start route guidance.

The above is the flow of another example of the route setting process. According to another example of the route setting process, even if the driver who is the user does not set the route, it becomes possible not only to receive route guidance, but also to set the route by date. . Therefore, for example, by including a different route in the route information in advance for a special day when the route is different from the usual route, it is possible to automatically set the different route on the special day and provide route guidance. becomes.

The above is an example of an embodiment according to the present invention. According to the route guidance device according to the present embodiment, route guidance can be received even if the driver, who is the user, does not set the route.

However, the invention is not limited to the above embodiments. Various modifications of the above embodiment are possible within the scope of the technical idea of the present invention.

For example, the route information 121 shown in the above embodiment is edited by the route editing unit 119 via an editing interface, but the present invention is not limited to this. For example, it may be edited by a cloud server or the like and received by each route guidance device 100 at a predetermined timing. By doing so, it is possible to remotely edit the route information, so that operation management is made more efficient.

Alternatively, in the route setting process, a route whose time and position substantially match is specified. If a mobile object is located nearby, route guidance may be applied as the selected route for the mobile object. By doing so, in the case of a route bus or the like, it is possible to avoid a phenomenon in which a plurality of buses waiting at the same time are set on the same route at a bus depot that is not the operation start position of the route. This is because, after each bus has dispersed and moved, if the bus is approaching the operation start position at the operation start time, the route is set as the selected route.

Further, each of the above configurations, functions, processing units, processing means, and the like may be realized by hardware, for example, by designing them in an integrated circuit. Moreover, each of the above configurations, functions, etc. may be realized by software by a processor interpreting and executing a program for realizing each function.
